LUNGS AND THORAX Flashcards
Portion of the body, extending from the base of the neck superiority to the level of the diaphragm inferiorly
Thorax
Located in the distal portion of the trachea
Lungs
This part of the respiratory system is located in the thorax and constitute the lower respiratory system
Bronchi
The outer structure of the throax is referred as
Thoracic cage
It contains the respiratory components
Thoracic cavity
The Jurassic cage is constructed of the sternum with how many pairs of ribs, how many thoracic vertebrae?
12
It provides support and protection for many important organs, including those of the lower respiratory system
Thoracic cage
It lies in the center of the chest interiorly
Sternum/breastbone
The sternum is divided into three parts. What are those?
Manumbrium
The body
Xiphoid process
This part of the sternum connects laterally with the clavicle and the two pairs of ribs
Manumbrium
It is a huge shape, indentation located on the superior border of the manubrium, and considered as an important landmark known as?
Suprasternal notch
This landmark is a Bony Ridge can be palpated at the point where manumbrium articulate with the body of the sternum
It is also the location of the second pair of ribs and becomes a reference point for counting ribs and intercourse of space
Sternal angle (angle of louis)
True or false
The first pair of ribs curves up immediately under the clavicle, so that only a small portion of these ribs, and the first interspaces are not palpable
False
(Palpable)
What is the range of the number of ribs that are easy to count because of their articulation with sternal body
Rib 2 to 6
This next pairs of ribs connects with the cartilage of the pair lying superior to them rather than to the sternum
Ribs 7-10
The configuration forms an angle between the right and left coastal margin meeting at the level of the xiphoid process. This angle is commonly referred to as?
Costal angle
What is the normal degrees of the coastal angle and if increase it is due to the long-standing hyper inflation of the lungs due to emphysema?
Less than 90 degrees
The spinous process of the seventh cervical vertebrae is also called as
Vertebra prominens
The lower tip of scapula is at the level of what rib
7th or 8th
What are the vertical reference lines called?
Midsternal line
Right and left midclavicular lines
Lateral vertical lines are
Anterior axillary line
Midaxillary line
Posterior axillary line
The Jurassic cavity consist of the _____ and the ____ and is lined by _____
Mediastinum
Lungs
Pleural membrane
It is the central area in the thoracic cavity contains the trachea, bronchi, esophagus, heart, and great vessels
Mediastinum
A flexible structure that lies an interior to the esophagus begins at the level of the cricoid cartilage in the neck approximately 10 to 12 cm long in an adult with C shaped rings of hyaline cartilage (maintain shape and prevent from collapsing during respiration)
Trachea
